Question

Hydrostatic movement in coelenterata annelida and echinodermeta

Answer 1

Answer:

Hydrostatic movement occurs in invertebrates where 'muscles contract' to change the shape of an organism's coelom which help in the production of the pressure of the certain fluid which is filled up in the fluid-filled cavity. This pattern is followed by the 'coelenterates', 'annelids', and 'Echinodermata'.
